voltage induction due to changing magnetic field

Robert Nawrocki

hello, I'm a relative newbie to comsol. what I'm trying to do is (I think) relatively easy, but I have no idea how to tackle it. what I need to do is model voltage induction in a coil due to a changing magnetic field. I know...   Read more »

AC current induced oscillations of electrothermal actuator driven by the Joule heating.

Olzhas Tazabekov

Hello everybody, I'm trying to simulate a resonance mode oscillations of bimorph electrothermal actuator driven by Joule heating through AC current. So far I've been trying to realize it through harmonic perturbation. So,...   Read more »

3D and 1D EM field scale difference

Harutyun Melikyan

Dear experts of Comsol and Moderators. I have a question. I design ICP chamber and get the data of EM fields. Normals... Actually 3D data scale shows like En=250V/m, Hn=130A/m, but when I do Cutline and check 1D datas, It...   Read more »

Urgent research problem: How to solve PDE systems( 2 PDEs 2 unknown u1,u2 coupled in 2 PDEs) in Comsol 4.0????

Liang Tian

1.Each PDE is composed of u1,u2. How to set up the coupling process? 2. The spatial dependence for this problem can be reduced to 1D. du/dx But it is a 2D rectangle. The laplcian operator will also consider another...   Read more »

Electric field distribution of microelectrodes

Bashar Yafouz

Hi everyone, I am a new user to Comsol. I want to see the electric field distribution of a set of microelectrodes. The frequency of my AC excitation signal is in MHz. 1- I have chosen RF module to do this task. Is that...   Read more »
